ASK TON: I'm A Lésbian But Haven't Enjoyed Séx So Much Since I Slépt With A Couple Of Men

I'm confused. I'm a lésbian who came out a few years ago. I first started sleéping with other women while I was in my teens, before I ever slépt with a man. 
But the thing now is that at college, while I still thought I was straight, I slépt with two different men.
I am very attracted to women, but since these experiences with men, I have been much more nervous and self-conscious and haven't enjoyed s** as much.
Pls advice me, what should I do?
